Tis (Tumour in situ)

Tis means carcinoma in situ.

Doctors use the ‘T’ part of the TNM system to stage cancer of the larynx. They call this the T stage. The T stage refers to how far your cancer has spread within the larynx and surrounding tissue.

The exact T staging of laryngeal cancer varies. It depends on which part of your larynx the cancer started in. Cancer can start:

  • above the vocal cords (supraglottis)
  • on the vocal cords (glottis)
  • below the vocal cords (subglottis) - this is rare

Tis

Tis means tumour in situ. The cancer is very early. It is contained in the top layer of the skin like covering of the larynx (mucosa) and has not spread into any surrounding tissue. 

Treatment

The surgeon might completely remove the abnormal area when you have the biopsy. Or you might have laser treatment.

If the cancer cells come back again you might have further laser surgery or radiotherapy.
